The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf coming up at Jaconé, with a real standout session that’s got my heart pumping. The water’s sitting at a warm 73°, which is bang on average for this time of year, so no surprises there.
The action kicks off Thursday morning, the 10th of September. It’s not the biggest, but man, it’s clean. We’re looking at a 4ft S swell with a 12-second period, and the wind is glassy out of the north. That’s a recipe for some fun, user-friendly waves. The combined energy is moderate (419), so there’s enough push to get you into something. This pattern holds through the afternoon, with the swell nudging up to 4ft and the wind switching to a glassy east. It’s a good, gentle start.
Friday the 11th is where things start to get interesting. The morning brings a 4ft S swell, but the period jumps to 14 seconds – that’s a proper groundswell. The wind is a clean cross-off from the ENE, and the combined energy is up to 816 (moderate). This is going to produce some nicely shaped, lined-up waves. The afternoon holds similar quality with a 4ft S swell.
Saturday the 12th is a wipeout. The swell drops to 3ft, and the wind goes onshore or cross-on, making a mess of things. Sunday the 13th is a bit of a mixed bag – the swell is bigger, around 6ft, and the energy is still moderate (486), but the period drops to a short 9 seconds and the wind is a bit messy. It’s marginal.
Monday the 14th has a messy morning with a fresh breeze, but the afternoon is a total redemption arc. The wind goes glassy out of the north, and we get a 4ft SSE swell with a 9-second period and strong moderate energy (558). The conditions are clean. Tuesday the 15th morning is also clean, with a 3ft S swell, but the afternoon gets blown out by a strong onshore wind.
We have a bit of a lull in quality from the 16th, with onshore winds and messy conditions, until we hit the first real standout. Thursday the 17th morning is looking special. We’ve got a 6ft S swell with a 9-second period, but the wind is a clean offshore from the ENE, and the energy is strong (816). That’s going to be clean and punchy. The afternoon is also worth noting, with a bigger 8ft S swell, but that’s getting into expert territory with a moderate breeze.
Friday the 18th morning is another beauty. A 5ft S swell, a moderate offshore wind from the ENE, and clean conditions. The energy is strong (670). Then Saturday the 19th is a gem. The morning is clean with a 4ft S swell, 13-second period, and a light offshore. The afternoon is a glassy dream with a 4ft S swell. The combined energy is moderate to strong (791 and 585). This is the period to book a day off work.
The waves drop right off from the 20th, with tiny surf and poor conditions through the 22nd and 23rd. There’s a gap of a few days of small, mediocre surf.
But hold on, because the biggest standout is coming. On the 24th of September, Thursday morning, we’re looking at an excellent swell for experienced surfers. A 6ft S swell with a 12-second period, clean light offshore winds, and a very strong combined energy of 1130. This is a serious session.
Then, the absolute cherry on top is Friday the 25th of September. Morning sees a 6ft S swell, a 14-second period – that’s a very long period groundswell – with a gentle offshore from the NE. The energy is massive at 1604. This is a serious, powerful, clean swell. It’s going to be breaking with a lot of energy, so at a beach break it might be a bit straight, but at a point or reef, it will be epic. The afternoon is also solid with a 6ft S swell. This Friday is the one to circle on the calendar, but remember, it’s a long way out, so keep an eye on the forecasts.
Stay stoked, and I’ll catch you in the lineup.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
